Abstract
A method and a system for the treatment of organic hazardous wastes from plant waste and associated wastewater treatment processes, whereby the waste is either introduced directly, or continuously separated from wastewater, and routed to a bioreactor, and whereby no organic solids are generated for further offsite disposal. The system disclosed includes a bioreactor, containing selected bacteria, untreated sludges, and recirculated biomass, and a liquid/solid separator allowing water to be utilized elsewhere in the system and returning solids to the bioreactor. The biodegradation process, initiated continuously, converts hazardous organic constituents in waste stream and wastewater sludges from plant operations to inert materials, for extensive periods of operation, without the need for solids removal, external solids treatment or disposal.
